Water quality

The rising atmospheric CO2 level is continuously driving the dissolution of more CO2 into the oceans, and some emission scenarios project that the surface waters may reach 1000 ?atm by the end of the century, write Fredrik Jutfelt and Maria Hedgrde, University…

Kassaye Balkew Workagegn, Hawassa University, Ethiopia, conducted this study to investigate the growth performance, feed utilization efficiency and survival rate of juvenile Oreochromis niloticus reared in aquaria at different water temperature.

In the Baltic Sea, two cod stocks evolve independently. Also the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possibly due to the irregular distribution of water masses of different sal…

Ocean acidification has a variable impact on the growth and survival of marine invertebrates. Larval stages are thought to be particularly vulnerable to environmental stressors, and negative impacts of ocean acidification have been seen on fertilization as wel…

Previous studies have documented that exposure to elevated Carbon dioxide (CO2) causes impaired antipredator behavior by coral reef fish in response to chemical cues associated with predation. However, whether ocean acidification will impair visual recognition…

Plastic debris litters aquatic habitats globally, the majority of which is microscopic (< 1 mm), and is ingested by a large range of species. Chelsea M. Rochman et al, University of California, US, show that fish, exposed to a mixture of polyethylene with c…

Marine food webs are the most important link between the global contaminant, methylmercury (MeHg), and humanexposure through consumption of seafood. Jennifer A. Dijkstra et al, Wells National Estuarine Research Reserve, US, look at how warming temperatures may…

Temperature is one of key environmental parameters that affect the whole life of fishes and an increasing number of studies have been directed towards understanding the mechanisms of cold acclimation in fish.

There is an increasing need to evaluate the links between the social and ecological dimensions of human vulnerability to climate change. Joshua E. Cinner et al, James Cook University, Australia, use an empirical case study of 12 coastal communities and associa…
